MAINTAIN CONSTANT TENSION – The ultrasonic sensor is used for maintaining constant tension when using a brake for producing unwind (payout) tension, or when using a clutch for rewind tension.
The sensor measures the diameter of the roll & sends a 0-10 VDC signal directly to the Placid PS power supply . Connect the ultrasonic sensor to the Signal Isolation Card when using the PST power supply. Torque is automatically varied as roll size changes, to keep tension constant. Tension is adjusted by a remotely mounted potentiometer. The sensor measures distances by sending an ultrasonic pulse of sound, and then measuring the time for the return echo pulse.
